The mathematics department of a college has 7 male​ professors, 6 female​ professors, 12 male teaching​ assistants, and 7 female
Natalka [10]

Answer:

0.78125 or 78.125%

Step-by-step explanation:

Male professors = 7

Female professors = 6

Male T.A. = 12

Female T.A. = 7

Number of people in the department = 32

The probability that the selected person is a professor or a male is given by the probability that the person is a professor added to the probability that the person is a male, minus the probability that the person is a male professor:

P( P\ or\ M) = P(P) +P(M) - P(P\ and\ M)\\P( P\ or\ M) =\frac{7+6}{32}+ \frac{7+12}{32}- \frac{7}{32} \\P( P\ or\ M) = 0.78125 = 78.125\%

The probability is 0.78125 or 78.125%

3. In order to become a member of the library-all-star-members club, there is a $40 sign-up fee and a $2 monthly fee. Write an e
eduard

Answer:

$78

Step-by-step explanation:

In the equation y = 2x + 40, x represents the number of months the member is a part of the club.

We are given that a certain member is part of the club for 19 months, so we substitute the number 19 in for x:

y = 2x + 40 = 2 * 19 + 40 = 38 + 40 = 78.

Thus, the total cost is $78.

Hope this helps!

Kaitlin buys 9/10 of a pound of orange slices. She eats 1/3 of them and divides the rest equally into 3 bags. How much is in eac
frozen [14]
I found how to solve this by pretending the /10 wasn't there and divided 9/3= 3. Next, I subtracted 9-3=6, and because she is splitting 6 into 3 bags she will have to divide 6/3= 2. So in each bag there will be 2/10 pound of orange slices.
